At the same time, the procedure focuses on the protection of autumn and winter(cell trays). Cover with plastic film for 5d, remove 14d after covering, and sown after the drug is fully evaporated. For seedling seedlings, a 126-well plastic plug is used, and a 2:1 volume ratio of the charcoal and vermiculite matrix is used. When spreading to the surface of the seed and drying it, mix the fine sand with 5 times the volume of the seed(3.54inch plastic plant pots), place it in a clean pot, cover the plastic film, and germination at 18-20 °C.(wholesale 128 cell grass plug trays canada)

After emergence, spray water once a day in the morning or evening(seed starting trays wholesale). The amount of water is subject to water seeing the surface. After 3 to 4 days, the water is poured once to reach the dry at noon and see the wet in the morning and evening. When the seedling grows to 5 to 6 leaves, it controls moisture and prevents it from growing. Gradually remove the sunshade net, and remove the sunshade net when it is 2 leaves(4.33inch plastic nursery pots), and carry out the seedlings once, the seedling distance is 3cm, and expand the nutrient area.

The seedling temperature is controlled at 15-20 °C(black plastic nursery pots). Moisture management keeps the soil dry and wet. In order to increase the yield per unit area, the density should be increased appropriately when planting, and the plant spacing (15-20 cm)×10-15 cm. To keep the soil moist, carry out the second top dressing, apply ammonium sulfate 450kg/hm2, and water with fertilizer(3.54inch plastic nursery pots). The heat and cold resistance of celery is not as good as that of celery, and it will be frozen below 0 °C.

(wholesale 128 cell grass plug trays canada)If the growth is weak and the fertilizer is lacking, the urea can be applied 8g/m2 in 4 to 5 leaves, and it is applied with watering(wholesale nursery pots). The seedling period is 60-70 days, the plant height is 10cm, the petiole is short and thick, the degree of development is large, 8-9 leaves, the main root is deep, and the roots are more. In time, the spring planting is shorter due to the shorter growth period, and the planting area is smaller(3.94inch plastic plant pots). After high temperature season, the well water should be poured in time to lower the ground temperature.

In the middle and late November, the greenhouse film is covered for heat preservation(plastic nursery pots wholesale), and the slow seedling stage (10-15 days after planting) should be poured in small water. When the seedlings are watered, the fertilizer is applied with ammonium sulfate or urea 300kg, and the seedlings are less watered for 20d. The seedlings are favorable for root system and heart leaf differentiation(4.13inch plastic plant pots). After the seedlings are transferred to the cool season, they enter the vigorous growth period.

The celery seedlings are generally not topdressed(plastic nursery pots manufacturers). Note that the commercial celery and solid celery require a single plant weight of 0.5 to 1.5 kg, the celery plant spacing is (25 to 30) cm × (25 to 30) cm, and other solid celery rows are 20 cm × (10 to 12) )cm. In the growth period of stems and leaves, 0.3% ~ 0.5% potassium dihydrogen phosphate can be sprayed 2 to 3 times(4.33inch plastic plant pots), and other micro-fertilizers such as boron fertilizer and harvesting treasure can be sprayed to improve yield and quality.(wholesale 128 cell grass plug trays canada)

Ventilation is required during the day(plastic nursery pots), and the temperature in the shed does not exceed 25 °C during the day and 5 °C during the night. It is also possible to adopt colony planting, with a row spacing (20 to 25) cm × (20 to 25) cm, and to ensure that the number of plants is about 450,000 plants/hm2. The autumn planting period is long, generally 75 to 100 days. Nitrogen is the main factor throughout the growth period(3.94inch plastic nursery pots). Avoid using human excrement to avoid causing rotten heart and rotten roots.
